I've tried a few of their products, and my top two are Emerge and Max Pro. NO2 Maximus According to the product description, Emerge is a powerful fat loss and body composition slenderizing system specially formulated to inhibit appetite, promote the release of fat from stored fat cells and accelerate the burning of fat for fuel. Boy do I love this product. I get the perfect amount of energy without my heart wanting to jump out of my chest. I haven't used it enough to observe it's slenderizing ability, but I'm sure in a few months my slender body will soon Emerge. I've tried some of the different flavors, each one better than the last. I haven't tried a flavor that I didn't like, however, my favorite is watermelon. http://www.lumagenexuk.co.uk/no2-maximus-and-ht-rush/
